To all cli/0m t may concern: V nipulation as often as re uired of the cl Be it known that I, JAMES B. MULLAY, aV 2.

For the purpose l 'Whatconstitutes my invention will be of such adjustment, I prefer to employ a hereinafter specied in detail and succinctly clamping yoke 12 which beingsecured as by set forth in the appended claims. screws 13 to the fixed arm 8 is provided In the accompanying drawings: Figure l uponopposite sides with wing bolts 14 and 80 is a side elevation of my apparatus complete 15 w ich oppositely impinge against the applied as in use.

The extent of such substantial longitudinal coextension with a adjustability as is required is such as to be saw blade 4. The office of the rail 3 is to better understood 'in the art of saw filing allocate my device to its work, in respect to than it would. be practicable to set forth or 10o which it proceeds in step by step adjust` necessary to attempt in this specification adment lengthwise of the rail 3, through ma- Y dressed, as it is, to one skilled in that art.
